3M Hookit Interface Pad 28845, 3 in x 4 in, Case of 10

• Applies effortlessly between Hookit discs and Hookit back-up pads for quick changeouts
• Ideal for sanding curves, angles and contours
• May include Clean Sanding hole configuration to clear dust from the work surface, increasing disc life
• Medium density foam provides additional flexibility on contours

The 3M Interface Pad is a 1/2-inch thick, medium density foam pad that provides additional surface conformability when used with a 3M Hookit backup pad on a 3M Random Orbital Sander. The additional conformability helps when sanding critical surfaces with fine grade abrasives, after leveling and refining sanding steps are complete, but before final surface finishing steps.

Conformability Protects Your Tools and Your Work Surface
Placed between the backup pad and the abrasive disc or sheet, the 3M™ Interface Pad provides additional conformability when sanding rounds and profiles, and helps operators reach internal angles.

The Clean Sanding Option – No Alignment Required
Some of these interface pads are designed to work with our 3M Clean Sanding system to maximize dust extraction, and must be used with a 3M™ Clean Sanding Backup Pad on a self-generated or central vacuum tool. Our 3M™ Clean Sanding dust-management system evacuates dust from the work surface better than 5 or 6-hole products, dramatically increasing disc life and maximizing cut-rate. Optimized with a self-generated vacuum sanding tool fitted with a Clean Sanding filter bag (sold separately), or a when used with a central vacuum system, the Clean Sanding system provides dust extraction from the air surrounding the tool, as well as directly from the work surface. This reduces loading of the disc and adds life to the abrasive. Additionally, reducing dust in the air improves working conditions.

3M™ Clean Sanding Interface Pad is available for use with 5 inch Clean Sanding Disc Pads and discs or 3x4” Clean Sanding Pads and sheets. Both feature a unique multi-hole pattern designed to maximize dust evacuation, extending the abrasive's life, improving results and keeping the air clean as well. For maximum dust extraction when using 3M™ Clean Sanding Interface Pads, align the holes in the interface pad with the holes in the back up pad, when installing the interface pad. The unique, multi-hole design of 3M™ Clean Sanding Abrasive sanding discs do not require alignment on the backup pad or interface pad, further saving you time and hassle.

The 3M™ Hookit™ System
We integrated the Hookit™ attachment system to make abrasive changes quick and easy, enabling repeated use and reducing material consumption.

3M Science Optimizes Industrial Abrasives
At 3M, we pay attention to every detail of the abrasive process, from discs to tools to all the accessories in between. Engineered with quality foam construction, Hookit™ backing and the unique hole design on the Clean Sanding options, 3M™ Interface Pads are an excellent example of how 3M uses science to continually improve abrasive operations and help businesses like yours operate faster, better and more efficiently.
